6 Claims. i

This invention relates to improvements in a spool stripper, and has for its primary object to remove that part of the roving or roping which lies close to the body or core of the carding spool.

In the textile industry, it is a matter of common knowledge that the first few turns of roping or roving about the core of a spool upon which it is wound is unsuitable for the production of yarn, and consequently it is customary to leave the first few turns of the roving or roping on the spool or bobbin, and this material is discarded as waste. Before the spool or bobbin can be reused, however, it is necessary that these turns of roving be removed, and to this end it has been common practice to draw a knife along the barrel of the spool so as to cut the roping or roving free. Such procedure, unless conducted with extreme skill, injures the barrel of the spool and in the case of a spool having a wooden barrel, the sharp edge of the knife is quite apt to leave slivers which not only render the spool dangerous to handle by the employees of a textile mill, but also are apt to injure the roving, roping or yarn that later may be wound on the spool. It has not been infrequent that the operation of drawing a knife longitudinally along the surface of the spool has so damaged the spool barrel as to render it wholly useless.

Another object of the present invention is to avoid damage to the barrels of carding spools, bobbins, and the like.

The above and other objects may be attained by employing this invention, which embodies among its features passing a carding spool downwardly in a vertical path between a pressure roll and a rapidly revolving stripper roll by which the roping or roving is caught and unwound from the spool, removing the waste from the stripper roll and depositing it in a suitable hopper from which it may be discharged into storage bins for subsequent disposal.

Other features include a pair of spaced, vertically extending guides for the reception of the ends of the trunnions carried at the ends of the carding spool, a pressure roll and a stripper roll supported in spaced parallel relation on opposite sides of the guides for engaging the spool barrel, a waste'reinoving roll adjacent the stripper roll for taking the waste from said stripper roll, a comb for stripping the waste taken by the secondmentioned roll from the stripper roll, a hopper into which the waste is deposited by the comb, and means to arrest the carding spool in proper position between the pressure and stripper rolls to cause the waste carried by the barrel thereof to be removed.

In the drawings:

Figure 1 is a top plan view of a waste stripper embodying the features of this invention,

Figure 2 is a side view of Figure 1, and

Figure 3 is a longitudinal sectional view taken substantially on the line 3-3 of Figure 1.

Referring to the drawings in detail, this improved stripper comprises a pair of side frames designated generally I0, each of which comprises a base member I l front legs i2, rear legs l3, and a horizontal supporting bar Hi. These frames H! are held in spaced parallel relation by transversely extending bars I5, and extending vertically from the inner side of each frame are intermediate standards It which are arrangedsubstantially midway between the ends of the bars I l and it. A similar vertically extending standard ll is attached to the inner face of each frame It) adjacent the front leg l2 thereof and is coextensive with the standards It previously mentioned. Extending downwardly at an angle from a point near the top of each standard ill to a point somewhat below the top of each standard i6 is an inclined guide bar l8, and extending downwardly and forwardly from a point somewhat below the horizontal bar M on the standard It is an inclined bar IS, the lower end of which joins the standard ii at a point somewhat below its junction with the standard it. The bars l8 and i9 and the standards I! are provided, on their inner faces, with aligning grooves 20 and 2! which, as illustrated, converge toward the standards it and join the upper and lower ends of grooves 22 formed in the standard It. The grooves 253, 2|, and 722 are of a width sufficient to receive the trunnions of the carding spools to be stripped, as willbe more fully hereinafter described.

Carried by the horizontal bars M on one side of the standards iii are aligned bearings 23 and arranged an equal distance from the standards it on the opposite sides are bearings 23'. Rotatably mounted in the bearings 23 is a shaft 26 which extends parallel to a shaft 2d mounted in the bearings 23. Carried by the shaft 24 nearest the front of the machine is a pressure roll 25 which cooperates with a stripper roll 25 mounted on the opposite shaft in holding a spool to be stripped against said stripper roll. The shafts 24 and 2d are each provided with a pulley 26 which pulleys have driving connection with each other through the medium of a, belt 27 so that when the shaft 2:: is rotated, the shaft 24 will rotate in the same direction in unison therewith. A drive pulley 2S is attached to the shaft 24 and has driving connection through a belt 29 which is trained over a drive pulley 30 carried by the main drive shaft of the machine to be more fully hereinafter described. Mounted in suitable bearings 3| carried by the bars I4 is .a shaft 32 carrying a transfer roll 33 which is adapted to run against the stripper roll 25 to take the waste therefrom. A conventional mechanicalcombf3'4" is positioned near the periphery of the transfer roll- 33 so" that as the transfer roll rotates and gathers the waste from the stripper roll 25, the comb will serve to strip the waste from the transfer roll 33. A hop.- per 35 is positioned below the transfer roll 33" so that as the waste is stripped from the roll, it will be deposited in the hopper and may be withdrawn therefrom through a tube 36 connected with a blower (not shown) to create'a draft through the hopper 35 and tube 36 which will remove the contents of the hopper and deposit it in suitable bins (not shown) for subsequent disposal. Attached to one end of the shaft 32 is a pully-3Twhich has driving connection through the medium of a belt 38 with a pulley 39 carried by the shaft 24 so that when the rollers 25 and. 25 are set in motion, the transfer roller33 will also be driven in-the same direction.

Mounted in suitable bearings 40 carried by the standards 16 is a main drive shaft 4| carrying a pulley 42 which has driving connection through the medium of a'belt 43 which extends around thedrive pulley 44- of aprime mover 45-such as an electric motor. main drive shaft is equipped with the pulley: 30 and it will 'thus be seen'that when the prime mover 45' is operated, the stripper roll 25, the pressure roll 25' and the roll 33 will also be driven. A'suitable endless belt 34' establishes driving connection between tliemaindriveshaft'fl and the comb 34.

Rotatably mounted in suitable brackets 46 carried by the horizontal bars l4 adjacent their forward ends is a shaft, adjacent-opposite ends of-which are-fixed upwardly extending levers 48. A hand lever 49is secured intermediate the ends of the shaft 41 and to the lowerend of the hand lever'is attached one end of a retractile coil spring 50, the opposite end of which is connected to the adjacent I cross bar I: Slidablymounted in sleeves 5! carried-by. thebars I4 are bolts 52 which are-connected, as at 53-, to the levers 48 and theopposite ends of these bolts are upwardly offset, as at 54, to move horizontally between the ends ofone of the rolls 25 and 25' and the standard It at a point slightly below the horizontal axes of the shafts 24.

When it is desired to strip the waste roving or ropingfrom a'cardin'g spool or' bobbin, the spool S is placed bet'weenthe standards I 'l at the upper ends of the groove'm' and allowed to move by gravity down the groove, as suggested in' the dotted'lineposition in Figure 2, until the trunni'ons on the ends of the spool encounter theofiset portions 54 of the bolts 52'. At'this' point, downward movement of the spool S is arrested and it is in position between the stripper roll 25and pressure roll 25 so that the'waste contained by the'spool will be removed. Simultaneously with the removal'of th'e'waste from the spool S, the roll 3Iwill remove the waste from the adjacent roll 25-and move it intoposition to be received by the hopper 35 as' the waste is being stripped from theroll 33 by the comb 34; When the waste has been completely removed-from the spool S, pull is exerted-on-the'ihan'd lever 49 thus rocking the shaft against-the tension of the spring 50 and withdrawing the bolts from their position beneath the trunnions on the spool S. The spool will thus be freed to descend through the grooves 22 and will be discharged through the grooves 2| to the front of the machine near the floor. In this way, the waste may readily be stripped from carding spools Without injury to the barrels thereof so that they may be used repeatedly at a great saving'of both labor and expense; Moreover, no danger of slivers beingformed on the surface of the spool barrel will be encountered and hence the device will contribute materially to the safety and comfort of textile workers.

The stripper rolls herein referred to may be of any conventional type, such for instance, as those disclosed in the patents issued to Dronsfield, August 6, 1918, No. 1,274,522; to Terrell, April 28, 1925', No. Re. 16,053; and to Crossland, June '7, 1927, No; 1,631,920.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction and combination and arrangementof parts may be resorted to without departing from the spirit and scope of the invention as claimed.
